Abstract

Starting from o-anisidine, alkylated 8-hydroxyquinolines 2 and 8-aminoquinolines 3 were obtained. From the latter, dialkylsubstituted 1, 10-phenanthrolines 5 have been prepared in good yields. Reaction of unsubstituted 8-aminoquinoline under the same conditions, yielded monoalkylated 1, 10-phenanthrolines 4.
